OSCAR C. WHITE, OF WICHITA, KANSAS.

WRENCH.

SPECIFICATION forming part of Letters Patent No. 390,422, dated October2, 1888.

Application filed May 2, 1888.

To all whomI it may concern:

Be it known that I, OsoAR C. VJHTE, of Vichita, in the county ofSedgwick and State of Kansas, have invented a new and Improved Wrench,of which the following is a full, clear, and exact description.

This invention relates to wrenches, and has for its object to provide awrench which can be used with nuts of various sizes and shapes.

The invention consists in a wrench constructed as hereinafter describedand claimed.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar figures of reference indicatecorresponding parts in both the views.

Figure lis a View of the invention; and Fig. 2 is a horizontal sectionthereof, taken on the line 00 :t of Fig. I.

In the construction of this invention the wrench consists of a plate, 1,formed with two openings or slots, 2, and intermediate projections, 3,between which is located a screw rod or shank, 4, having its endsextending into the openings 2, and one of said ends formed with asquare-ended sliding jaw, 5, and the other end with a notched slidingjaw, 6. The jaws 5 and 6 are kept in place by the straps or keepers 7,secured to plate l, and are operated by a thumbnut, 8, located in slots9 in the projections and engaging screw-rod 4.

The outer end ofthe opening 2 in which the jaw 5 is located is formedsquare, as at IO, by means of which, with the jaw 5, square- Shaped nutsmay be operated, and the outer end of the opening 2 in which the jaw Gislocated is formed with a notch, 11, by means of which, with the jaw 6,hexagonal nuts may Serial No. 272,560. (No model.)

be operated. Instead of the ends of the openings 2 and the jaws beingconstructed in the forms as just described, they may be made in anyother s'hape desired, both ends being adapted for hexagonal nuts, ifdesired. By means of this construction it will be seen that either endof the plate 1 serves asa handle for the jaw operating at the oppositeend, and that the jaw desired for use is easily adjusted by means of thethumb-nut 8, acting on the rod 4.

The wrench may be made of any suitable size and of iron or steel, andwill be found very convenient where nuts of different sizes and shapeshave to be manipulated.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

l. A wrench consisting of a handle formed with lengthwise slots, ascrew-rod with a jaw at each end located in the lengthwise slots of thehandle, and an operating thurnbsnut en gaging the screw rod7substantially as described. v

2. A wrench consisting of plate l, having openings 2, one of which hasthe square end 10 and the other the notched end 11, projections 3, withslots 9, in which is located thumbnut 8, the screw-rod 4, engagingthumb-nut 8, and having at one end the square-ended sliding jaw 5 and atthe other end the notched sliding jaw 6, and the retaining-straps 7,substantially as described.
